ABSTRACT
This chapter describes the synthesis of a bis(2-thienyl)-diketopyrrolopyrrole and 1,4,5,8-naphthalenetetracarboxylic acid diimide derivative having two ZnII-cyclens, the construction of deoxyribonucleic acid (DNA) templated multichromophore arrays, and the photoelectrochemical properties of the arrays in self-assembled monolayers on a gold substrate. Oligonucleotides are attractive molecules as construction materials for nanoarchitectures as well as for multichromophore arrays. To seek new types of photo- and electronic functions, it is conceivable to evaluate the fundamental properties of the π-stacked arrays with a finite number of chromophores and then use the findings as feedback to design multichromophore arrays. The formation of multichromophore arrays can be indicated by ultraviolet-vis titrations. The formation of the multichromophore arrays was characterized by using gel filtration chromatography using a size exclusion column. DNA-templated multichromophore aggregation suppresses the charge transfer complexation among the chromophore building blocks, and the multichromophore arrays exist stably without disruption of their structures at room temperature.
